JOSEPH K. SHARPE, JR., OF INDIANAPOLIS, INDIANA, ASSIGNOR IO TI-IEINDIANA MANUFACTURING COMPANY, OF INDIANAPOLIS, INDIANA, A CORPORATIONOF WEST VIRGINIA.

PNEUMATIC STACKER.

To all whom 'it may concern:

Be it known that I, Josnrir K. SHARPE, J r., a citizen of the UnitedStates, residing at Indianapolis, in the county of Marion and State ofIndiana, have invented certain new and useful Improvements in PneumaticStackers, of which the following is a speciw fication.

My invention relates to improvements in pneumatic stackers, and hasparticular reference to the material-receiving chamber thereof, in whichI provide means for positively defiecting toward the discharge fan thatportion of the material which falls into the chamber at the farthestside from said fan and away from the influence of its intake aircurrents, and by which means I am enabled to utilize an interiorlyunobstructed horizontally-arranged chamber of simple construction andformation, obviating the necessity of employing mechanical conveyersacross the width of the chamber, or inelining the bottom thereof whereno conveyers are provided, each of which arrangements must be especiallydesigned to meetthe various conditions existing incident to thedifference in form and dimensions of the many types of separators andthe peculiar' separating mechanisms embodied therein.

In the accompanying` drawings, which are made a part hereof, Figure l isan elevation of a stacker embodying my invention, and indicates themanner in which the material is treated; Fig. 2, a horizontal sectionalview on the dotted line 2 2 in Fig. l; and Fig. 3, a vertical sectionalview on the dotted line 3 3 in Fig. 2.

In said drawings the portions marked 5 represent the casing of thestacker, in one side of which is mounted a discharge-fan, 6, having theusual discharge chute, 7 connected therewith, which elements may be ofany ordinary or desired construction, and provided with any suitableoperating means, such for instance as indicated in the drawings.

As before indicated, the suction produced by the rotation of thedischarge fan 6 is effective only within a limited area in the strawchamber, 8, and as such chambers are of considerable width, it isnecessary, in order to insure efiicient operation of the stacker, thatall of the material issuing from Specification of Letters Patent.

Application filed July 13, 1908.

Patented Oct. d, i910.

serial No. 443,262.

l the separator be positively directed into the zone of action of thedischarge-fan, and to attain this result it is the common practice toprovide a straw chamber inclined from that wall of the machine oppositethe dis charge fan downwardly to the inlet of said fan so that thematerial may by gravity move into the influence of said fan, or, in someinstances, where the chamber has a horizontal bottom, to introduce amechanical conveyer therein for carrying the niaterial into the fan.

By my present invention I attain this result by means of a beater, 9, ofany desirable construction, located in the opposite side of the strawchamber to that of the discharge fan, and which, as indicated in thedrawing, is positioned transversely of the length of the chamber, beingpartially inclosed in an appropriate casing, as 10, above which Ipreferably provide a guide, l2, for directing the material onto thebeater. Said beater 9 is mounted on shaft, ll, which may be driven inany desired manner, either from the shaft of the discharge fan or from asuitable source on the separator, a simple and preferred arrangement,however, being that disclosed in Fig. 2, which consists of thecounter-shaft, l2, having a gear, 13, which meshes with gear, la, on thebeatershaft, 1l, said counter-shaft being driven from the discharge-fanshaft, l5, by means of belt, 1G.

As will be readily understood, when the machine is in operation, rotarymotion is imparted to the beater by means of the arrangement shown anddescribed, or as may be otherwise preferred, with the consen quentresult that material discharged from the separator into that side of thechamber falls directly onto said beater, and is impelled thereby (and byany air currents caused by its rotation) laterally across said chamberand toward the discharge fan and sufficiently near thereto to be actedupon by the air suction produced thereby, by which it is withdrawn intosaid fan and discharged through the stacker chute, as usual.

I claim as my invention:

l. A pneumatic stacker comprising a material-receiving chamber, adischarge-fan at one side thereof, a beater in the opposite side of saidchamber, a guide for directing material to said beater, and means foractuating said beaterl to impel material toward said discharge fan.

2. A pneumatic stacker comprising a material-receiving` Chamber7 adischarge fan at one side thereof, a beater at the opposite side of saidChamber7 a easing partially inclosing said beater7 a guide above saidbeater, and means for aettiating said beater to impel material towardsaid discharge fan.: 1G

In testimony whereof I atiX my signature in presence of two Witnesses.
